Any books on the anatomy of birds?

[Rostum]

Hey, so I am doing a research project and pseudo-thesis on animation techniques for birds (more specificly, I will be modelling/rigging and animating a Hummingbird, Golden Eagle and White Pelican for the 12 week research).

All the books I can find are for birding, but I want to find anatomy and how birds 'work'. Can anyone help me find books or documentries on the matter? I will be checking the state library soon enough, but thought I'd try around the Internet to see what I can find.

It's all I got in a Bio-medical library of 5200 books. I think it'll be hard for you to find it.
